...Powerful winter storm to produce significant impacts across parts of
New England and coastal Mid-Atlantic/Northeast on Saturday...

...Well below average temperatures will expand across eastern third of the
country this weekend before moderating next week; Great Plains warm up
this weekend...

An area of low pressure is forecast to develop off the Atlantic coast of
Florida this morning. This low will rapidly intensify as it travels north
throughout the day. Moderate to heavy snow and gusty winds are forecast to
materialize along the Mid-Atlantic and Northeast coasts this evening as
the low arrives off the coast of North Carolina. Some moderate to heavy
amounts are also likely to spread into parts of the Central and Southern
Appalachians. Heavy snow and intense winds are then expected to develop
over New England on Saturday as the Nor'easter continues to intensify off
the Northeast coast. Blizzard conditions are forecast from eastern Long
Island through much of coastal New England, particularly from southeast
Maine to Cape Cod. This will make travel nearly impossible. Significant
beach erosion and coastal flooding will also be a concern. Winter Storm
Watches and Warnings are in effect for much of the coastal Mid-Atlantic up
into the coastal Northeast. Winter Weather Advisories and Warnings are in
effect for parts of the Central/Southern Appalachians. The heaviest
snowfall is likely to fall across a swath extending from the Eastern Shore
of Maryland up through most of Maine where 6-12 inches are likely. Parts
of coastal New England, where blizzard conditions are forecast, may see
between 1-2 feet of snow with locally higher amounts possible,
specifically over coastal Massachusetts.

Bitter cold air will filter in behind the Nor'easter and plunge
temperatures across the eastern third of the country on Saturday. Highs
will be 15-25 degrees below average in most places. Temperatures will
begin to moderate across the region by Monday. Elsewhere, an Alberta
clipper system will bring light snow to the Upper Great Lakes on Saturday
night while a new system emerges to produce light rain and snow over the
Pacific Northwest. Anomalously warm air will expand across the Great
Plains this weekend.
